1, water quality requirements: Acer truncatum likes to grow in soft water with weak acidity and low hardness. Its congenital lip can't be closed, and its ability to control the water flow is poor. The water flow through its gills is small, and its oxygen absorption ability is not strong. The water body needs enough oxygen when it is cultivated.
2. Temperature requirements: the octopus generally lives freely at the water temperature of 20 ~ 30 C.
3. Feed management: The octopus has a messy diet, eats almost everything such as artificial bait, flakes, particles, red worms, bumper shrimp, water lice, etc., and is quite greedy. It is fed quantitatively every day, reasonably matched with bait nutrition, and regularly fed fresh shrimp and small fish, which is the artificial bait made for the octopus.
4, bacterial diseases: the symptoms are redness and swelling of the cheeks. In severe cases, the bleeding on the cheeks turns white, the eyeball is cloudy, the abdomen is swollen and stagnant, and the skin around the genital hole is congested and swollen.
5. Fungal diseases: It often happens in the alternating seasons of autumn and winter. Small wounds on the surface of fish are infected with mold, and the wounds are attached with gray fluffy water mold.
6. Parasitic diseases: It often occurs in the alternate seasons of autumn and winter and spring and summer when the water temperature changes sharply. The surface of diseased fish is full of white spots, which will cause bacterial diseases for a long time.
